Being a huge fan of Portal 2, I really wanted to have a root around in the game’s files and see what spoils I could find. Along with a variety of sound files and music (the Soundtrack that Valve have released is much better), I managed to stumble across the collection of silly posters dotted around the game and finally, the wall dioramas by the Rat Man. If you’re looking for these yourselves, they’re named diorama_tile1_01 through to diorama_tile1_05, all nabbed from pak01_dir.vpk.

The wall murals show the sequence of events leading up to Portal 2, from GladOS’s creation to Chell’s original trials and ‘escape’.
